Last semester, Mr. King kept track of how many times each student was absent.

Question

Student absences
0
2
4
6
8
10
What was the lower quartile of the number of absences?

Answer 1

To find the lower quartile (Q1) of the data set, we first need to organize the data in ascending order. The number of absences for the students is already listed in ascending order as follows:

0, 2, 4, 6, 8, 10

Next, we need to find Q1, which is the median of the lower half of the data. Since there are 6 data points in this case, we can split the data into two halves. The lower half of the data would include the first three values:

0, 2, 4

To find the median of this lower half:

1. Since there are three values, the median (Q1) is the middle number, which is 2.

Thus, the lower quartile (Q1) of the number of absences is 2.
